Alternate Pillow Block

[Kat Member Find all posts View Profile Close Kat]

I was visiting a nearby center recently and saw they had a new style of pillow block bearings for the sweep and table torque tubes. They were different from the OEM sheet metal types that like to break...they were sort of a casting type which did not have the two strap setup like the OEM. Are these a Stahls Seventys deal or what? Does anyone know if there is a Grainger setup like this that would work? It's time for me to order some pillow block assy's, but would like to get hold of those cast jobbies as they look much more durable that the two-strap style that likes to break at the worst possible time. Thanks guys.

Re: Alternate Pillow Block

The early 70's had cast iron pillow blocks, they were not self centering and were expensive.

They were replaced by the strap type.

John and Clutch,

Thanks for the insight. These pillow blocks actually look brand new whihch was why I brought up the Grainger thing. I looked thru the catalog and saw some of the cast types that had self-centering bearings. Wonder if this would work???

Re: Alternate Pillow Block

I have only seen 2 or 3 strap style pillow blocks break in 20+ years.

Re: Alternate Pillow Block

I've had to replace 3 in the 26 years I've been working on 70's. Inspect &amp; grease them regular, They'll last forever.

Re: Alternate Pillow Block

King, if you stay working on the 30's you will see more break. I seen more than 3 break on the 30's in the 11 years I worked on them.

<font size="2" face="Verdana, Helvetica, sans-serif">Jerry, Willey is right. The side that has the table gear train will break. When this happens the table will not spot pins. Reason: The sag
puts too much pressure on the spot solenoid lever and it will bind and not operate.

No, it definitely wasn't a 90s style as I have several of those throughout the house.

Re: Alternate Pillow Block

I think these may be Stahls. I bought two of them about a year or so ago. I have not yet used them. I will check, I think they are cast alum.

Re: Alternate Pillow Block

The reason the straps break on a 30 is because of machines running out of time and the sweep and table getting jammed. All this interaction is transferred to the TGT side through the spotting rod. Have never seen one break on the R.H. side of a 30's table.

A 70 or 90 seems to be a different story. With pressure being applied equal to both sides because of table and shuttle jams and tables banging off the pindeck looks like both pillow blocks are fair game.
